摘要
为估价心肌显像在 X 综合征诊断中的意义,用^(99m)Tc-甲氧基异丁基异腈对21例有典型心绞痛、冠状动脉造影正常、运动试验心电图阳性而诊断为 X 综合征的患者进行了心肌 SPECT 显像,并与17例临床有胸痛、冠状动脉造影正常、运动试验心电图阴性的非 X 综合征患者和26例冠状动脉造影证实为冠心病心绞痛患者的心肌显像进行对比。结果:21例 X 综合征患者经心肌 SPECT 检查11例有心肌缺血,其心肌缺血半定量计分为1.1±0.3,而冠心病心绞痛者心肌缺血计分为1.8±0.7(t=3.174 6,P<0.01)。故心肌 SPECT 显像可检出部分 X 综合征的心肌缺血,其缺血程度比冠心病心绞痛者轻。
PURPOSE To assess the value of myocardial imaging in the diagnosis of syndrome X.METHODS The study was performed with ^(99m)Tc-MIBI myocardial SPECT imaging in 64 patients.The patients were divided into three groups:group 1 had 21 patients diagnosed as syndrome X,group 2 had 17 patients with chest pain and normal coronary arteris without ST segment depression during exercise,group 3 had 26 patients with the angina pectoris and coronary stenoses≥50%.The myocardial SPECT imaging of the three groups was compared qualitatively and semiquantitatively.RESULTS Myocardial imaging identified 11 cases of myocardial ischemia from 21 patients with syndrome X.The isehemic score of myocardial imaging was 1.1±0.3 for syndrome X and 1.8±0.7 for patients with coronary heart diseasc(CHD) angina pectoris(t=3.1746,P<0.01).CONCLUSIONS My- ocardial imaging may partly show myocardial ischemia in patients with syndrome X.The extent of ischemia in patients with syn- drome X was significantly less than that in patients with CHD angina pectoris.
